Detailed explanation of asparagus spring planting techniques: master these points to grow asparagus well
Asparagus is a vegetable with very high nutritional value, ranking relatively high among vegetables in our country. Now that winter has arrived, the management work for asparagus has also become heavy. Many friends have already done the overwintering work to make things easier for the asparagus in the spring of the following year. However, during the transition between winter and spring, asparagus will inevitably be somewhat unadapted. Therefore, the planting methods should also be appropriately changed. So today, the editor brings you the spring asparagus planting techniques. Let's take a look together!
1. Seedling raising at the right time
The commonly used planting method for asparagus is sowing and raising seedlings. The method of sowing and raising seedlings can effectively improve the emergence of asparagus, enhance seedling quality, advance the maturity time, and expand the utilization rate of the land. When raising seedlings, choose fertile and loose sandy soil. The soil layer does not need to be too thick; keeping it at about 20 cm is sufficient. Before sowing, apply sufficient base fertilizer. The base fertilizer is mainly decomposed poultry manure, with phosphorus fertilizer as the main component. In addition, the temperature in spring has not yet fully risen, so after sowing, the seedbed temperature must be well controlled, ensuring it is around 20°C and not lower than 15°C.
2. Land preparation and fertilization
When raising seedlings, land preparation work should be carried out on the field where planting will take place. Asparagus is a perennial crop, so deep plowing should be carried out before planting. The soil pH value should not be too acidic or too alkaline; it should remain neutral. Therefore, when the pH value is unsuitable, neutralization work should be done well. Ensure that the field soil is sufficiently fertile and has strong ventilation and permeability. Asparagus has very poor waterlogging tolerance, so drainage ditches should also be dug well to facilitate later drainage work. Then, during land preparation, apply sufficient base fertilizer in combination to improve soil fertility and promote the growth of asparagus seedlings.
3. Field management
After planting, the goal should be to cultivate the growth of the asparagus roots. If the asparagus is too thin and small, then the nutrient ratio should be increased in a timely manner, and cultivation and weeding work should be done well. Then, according to the soil fertility and the growth conditions of the asparagus, apply additional fertilizer appropriately. After rain, pay attention to drainage; otherwise, it is very easy to cause the asparagus roots to rot. Around September is a relatively important period in asparagus growth, and the demand for nutrients will also increase greatly. So at this time, nutrients should be supplemented in a timely manner. During harvest, water reasonably to keep the soil moist and prevent the asparagus from drying and cracking due to lack of water.
4. Pest and disease control
Spring is also the season when various pathogens and pests regain their vitality, so the incidence of asparagus diseases in winter is very high. Therefore, pest and disease control in spring is also an indispensable management task. While strengthening field management and doing a good job in water and fertilizer work, the asparagus garden should also be disinfected regularly. You should understand the common pests and diseases of asparagus well, and then carry out pest and disease control work purposefully and in a targeted direction. If disease occurs, promptly remove the diseased plants, then check the cause and apply the appropriate treatment.
The above is a brief introduction to spring asparagus planting techniques. Asparagus has relatively weak disease resistance, so we must do these management tasks well to avoid unnecessary losses. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
